Description

Technical Field

[0001] The present invention belongs to the technical field of plastic preparation, and in particular relates to a system and method for preparing environmentally friendly and renewable plastic particles. Background Art

[0002] When recycling plastics and re-granulating them, the recycled plastic products need to be cleaned first, so as to facilitate subsequent processing such as melting, extrusion, and pelletizing, and avoid the plastic products containing too many impurities, which may cause damage to the subsequent processing equipment when the plastic products are added. Therefore, before melting the plastic products, the plastic products need to be added to a container filled with clean water for comprehensive cleaning. When cleaning plastic products in the existing technology, since the cleaning effect of stagnant water for immersion cleaning is poor, most of the time, running water is used to rinse the plastic products to ensure the cleaning effect and comprehensive cleaning degree. However, this method will generate a large amount of wastewater and waste water resources. At the same time, since it is difficult to rinse the inside of the plastic products, the cleaning effect is still poor. Therefore, a device that can improve the cleaning effect is needed. Summary of the Invention

[0003] In view of this, the technical problem to be solved by the present invention is to provide a device that can shear and crush plastic products during cleaning, thereby improving the cleaning effect.

[0004] An environmentally friendly and renewable plastic particle preparation system includes an inclined plate with multiple through holes, a shovel plate rotatably connected to the inclined plate, and multiple cutters connected to the inclined plate. The multiple cutters can move up and down in the vertical direction of the inclined plate.

[0005] The utility model also comprises two side plates fixedly connected to the inclined plate, and a horizontal plate fixedly connected between the two side plates.

[0006] The invention also comprises a partition arc plate which is slidably connected to the front side plate, and a shielding plate is slidably connected to the partition arc plate.

[0007] The method for preparing plastic particles using the environmentally friendly and renewable plastic particle preparation system comprises the following steps:

[0008] S1. Add the recycled plastic products into a cleaning container and add clean water into the cleaning container;

[0009] S2, moving the connecting vertical plate along the cleaning container, and operating the shovel plate to continuously rotate back and forth on the inclined plate to move the water and plastic products;

[0010] S3, operate the shovel to rotate to a position parallel to the bottom surface of the cleaning container, and slide the inclined plate downward on the connecting vertical plate so that the shovel contacts the bottom surface of the cleaning container;

[0011] S4, operate the connecting vertical plate to move along the cleaning container, after a period of time, operate the shovel plate to rotate to a perpendicular position with the inclined plate, and then slide the inclined plate upward on the connecting vertical plate to lift the inclined plate out of the water;

[0012] S5, operating the connecting frame to slide and causing the slide to slide on the connecting frame, so that the multiple cutters move to perform cutting;

[0013] S6. After the cutting is completed, the shovel is operated again to rotate to a position parallel to the bottom surface of the cleaning container, so that the cut plastic product on the inclined plate slides down;

[0014] S7, sliding the inclined plate downward until the rubber block contacts the plastic product, then operating multiple toggle plates to press on the rubber block, and sliding the L-shaped rod on the slide, so that the rubber block is continuously deformed and the connecting vertical plate is continuously moved along the cleaning container;

[0025] See Figure 2 、 Figure 3 、 Figure 4 、 Figure 9, shows a schematic diagram of an embodiment of the present invention that can improve the cleaning effect, further,

[0026] This system includes an inclined panel 101, which is provided with a plurality of through holes 102. A shovel plate 201 is rotatably connected to the inclined panel 101. A first motor is fixedly connected to the inclined panel 101 by bolts. A cylindrical shaft is welded to the shovel plate 201. The output shaft of the first motor is fixedly connected to the cylindrical shaft by a coupling. A plurality of cutters 303 are connected to the inclined panel 101. The plurality of cutters 303 can all move up and down in the vertical direction of the inclined panel 101. The inclined panel 101 can move up and down in the vertical direction.

[0027] The plastic products to be cleaned are placed in a cleaning container, and then clean water is added to the cleaning container to soak the plastic products. The shovel plate 201 is then operated to rotate back and forth continuously on the inclined plate 101, and the shovel plate 201 is continuously moved along the cleaning container, so that the shovel plate 201 continuously stirs the plastic products in the water, thereby facilitating cleaning. After stirring for a period of time, the shovel plate 201 can be operated to rotate to a position parallel to the bottom surface of the cleaning container, and then the inclined plate 101 is operated to move downward, so that the shovel plate 201 contacts the bottom surface of the cleaning container, and then the inclined plate 101 is moved horizontally along the cleaning container in the cleaning container, so that the plastic products in the cleaning container are gradually accumulated on the inclined plate 101 along the shovel plate 201. After a certain amount of plastic products are placed on the inclined plate 101, the shovel plate 201 is operated. 201 is rotated to a position perpendicular to the inclined plate 101, and then the inclined plate 101 is moved upward, thereby lifting the inclined plate 101 from the water. Since a plurality of through holes 102 are provided on the inclined plate 101, the water originally on the inclined plate 101 can naturally fall from the plurality of through holes 102, so that only a certain amount of plastic products remain on the inclined plate 101. Subsequently, the plurality of cutters 303 are operated to move downward along the vertical direction of the inclined plate 101, thereby cutting the plastic products and causing them to break. Subsequently, the shovel plate 201 is rotated to a position with the same inclination as the inclined plate 101, thereby causing the cut and broken plastic products to slide along the inclined plate 101 and the shovel plate 201 into the cleaning container. Since the plastic products have been cut and broken at this time, the water can fully contact the plastic products, thereby improving the cleaning effect.

[0028] See Figure 2-3 , showing a schematic diagram of an embodiment of the present invention in which a box structure can be formed on the inclined panel 101 to facilitate subsequent cutting processing, further,

[0029] The system further includes two side plates 103 welded to the inclined plate 101 , and a horizontal plate is welded between the two side plates 103 .

[0030] The two side panels 103 and the cross panel welded between the two side panels 103 form three box walls of a rectangular box. Then, when the shovel plate 201 is rotated to a position parallel to the bottom surface of the cleaning container and the inclined panel 101 is moved along the cleaning container, the plastic products can be located between the box walls formed by the two side panels 103 and the cross panel to prevent the contained plastic products from being separated from the inclined panel 101 due to the movement of the inclined panel 101. After the inclined panel 101 is lifted out of the water and the shovel plate 201 is turned back, the shovel plate 201, the two side panels 103 and the cross panel can cooperate to form a box-like space, which facilitates subsequent cutting operations and prevents the plastic products from sliding off the inclined panel 101 during the cutting process, thereby ensuring the cutting effect.

[0031] See Figure 7-9 , shows a schematic diagram of an embodiment of the present invention for facilitating batch cutting of packaged plastic products, further,

[0032] The device includes two side panels 103, one of which is located on the front side and is fixed with a trapezoidal slide. The separation arc plate 502 is slidably connected to the front side panel 103 through the trapezoidal slide. The front side panel 103 is fixedly connected to the third motor by bolts. The output shaft of the third motor is fixedly connected to the second lead screw by a coupling. The second lead screw is threadedly connected to the separation arc plate 502. A through slot is provided on the separation arc plate 502. A shielding plate 501 is slidably connected to the separation arc plate 502. An electric push rod I is fixedly connected to the separation arc plate 502 by bolts. The telescopic rod of the electric push rod I is fixedly connected to the separation arc plate 502 by bolts. The shielding plate 501 can shield the through slot.

[0033] When carrying out the loading work, the partition arc plate 502 is operated to slide along the front side plate 103 to the lower end of the inclined panel 101, and then the shielding plate 501 is slid upward, so that the through groove on the partition arc plate 502 is not blocked, so that the plastic products will gradually accumulate on the inclined panel 101 through the through groove on the partition arc plate 502. When the loading amount reaches the expected value, the telescopic rod of the electric push rod I is operated to retract, so that the shielding plate 501 blocks the through groove on the partition arc plate 502. At this time, the plastic products are located between the partition arc plate 502 and the horizontal plate fixed between the two side panels 103. Then the partition arc plate 502 is operated to open on the front side. The side panels 103 slide upward, causing the plastic products to be squeezed between the separating arc panels 502 and the horizontal panels. After the shovel panel 201 rotates to a vertical position with the inclined panel 101, the shielding panel 501 is operated to slide upward, causing the squeezed part of the plastic products to automatically slide down along the inclined panel 101, thereby being blocked by the shovel panel 201 and then accumulated on the shovel panel 201. Subsequently, multiple cutters 303 are used to complete the cutting task. After the cutting task is completed, the shovel panel 201 is operated to rotate, causing the cut plastic products to slide down along the shovel panel 201. The above operation is then repeated to complete the effect of batch cutting, thereby improving the cutting effect.

[0034] See Figure 2 、 Figure 3 、 Figure 4 、 Figure 10 , shows a schematic diagram of an embodiment of the present invention that facilitates cutting and breaking work, further,

[0035] This device also includes a T-shaped slide fixedly connected to the side plate 103 located on the rear side of the two side plates 103, and a connecting frame 301 is slidably connected to the T-shaped slide. A second motor is fixedly connected to the side plate 103 on the rear side by bolts, and a second lead screw is fixedly connected to the output shaft of the second motor by a coupling. A slot is provided on the connecting frame 301, and the slide 302 is slidably connected to the connecting frame 301 through the slot. An electric push rod II is fixedly connected to the connecting frame 301 by bolts, and the telescopic rod of the electric push rod II is fixedly connected to the slide 302 by bolts. Multiple cutters 303 are welded to the slide 302, and a plurality of spacing grooves 202 are provided on the shovel plate 201. The multiple cutters 303 can be respectively inserted into the multiple spacing grooves 202.

[0036] After the plastic product is partially slid down and blocked by the shovel plate 201 and then accumulated on the shovel plate 201, the shovel plate 201 is operated to rotate toward the inclined plate 101, so that the shovel plate 201 can firmly press the plastic product, and then the telescopic rod of the electric push rod II is operated to retract, so that the multiple cutters 303 are respectively inserted into the multiple spacing grooves 202 and pressed on the top of the plastic product. Then the connecting frame 301 is operated to slide left and right along the rear side plate 103, so that the multiple cutters 303 can reciprocate along the direction of the inclined plate 101, thereby completing the cutting task of the plastic product. The shovel plate 201 pressing on the plastic product can prevent the plastic product from moving at will during the cutting process, thereby affecting the cutting effect.

[0037] See Figure 5-6 , shows a schematic diagram of an embodiment of the present invention for facilitating changing the position of a plastic product to be cut, thereby improving the cutting effect, and further,

[0038] In this device, a groove is provided on the slide 302, and the vertical rod 404 is slidably connected to the slide 302 through the groove. The slide 302 is fixedly connected to the fourth motor by bolts, and the output shaft of the fourth motor is fixedly connected to the third screw via a coupling. The third screw is threadedly connected to the vertical rod 404, and a rectangular groove is provided on the L-shaped rod 401. The L-shaped rod 401 is slidably connected to the vertical rod 404 through the rectangular groove. The vertical rod 404 is fixedly connected to the electric push rod III by bolts, and the telescopic rod of the electric push rod III is fixedly connected to the L-shaped rod 401 by bolts. A plurality of toggle plates 402 are welded to the L-shaped rod 401.

[0039] After using multiple cutters 303 to insert into multiple spacing grooves 202 to complete a cutting task, the shovel plate 201 can be operated to rotate again to a vertical position with the inclined plate 101, and then the L-shaped rod 401 can be operated to slide downward so that the multiple toggle plates 402 contact the plastic products, and then the vertical rod 404 can be operated to slide left and right on the slide 302, so that the vertical rod 404 drives the multiple toggle plates 402 to repeatedly toggle the plastic products, thereby changing the position of the plastic products, and then the shovel plate 201 is used again to press on the plastic products, and then cut again, and repeat multiple times to cut the batch of plastic products multiple times, thereby further improving the cutting effect.

[0040] See Figure 7-8 , shows a schematic diagram of an embodiment of the present invention that can prevent plastic products from being mixed with iron recyclable items, further,

[0041] This device also includes a vertical rod welded on the connecting plate 503, and the connecting plate 503 is slidably connected to the separation arc plate 502 through the vertical rod. The separation arc plate 502 is fixedly connected to the electric push rod III by bolts, and the telescopic rod of the electric push rod III is fixedly connected to the separation arc plate 502 by bolts. A magnetic plate 504 is welded to the connecting plate 503.

[0042] During the process of regularly sliding the shielding plate 501 so that the plastic products are slid to the shovel plate 201 in batches for cutting, the connecting plate 503 can be operated to slide downward, so that the plastic products need to pass through the gap between the connecting plate 503 and the inclined plate 101 before sliding out of the through groove of the separating arc plate 502. A magnetic plate 504 is connected to the bottom of the connecting plate 503. The magnetic plate 504 can detect the plastic products as they pass through. If there are iron recyclable items in the plastic products, they will be directly adsorbed by the magnetic plate 504 for recycling to avoid waste of resources.

[0043] See Figure 6 , shows a schematic diagram of an embodiment of the present invention for dredging the through groove of the separation arc plate 502, further,

[0044] The device further includes a dredging arc plate 403 , and each of the toggle plates 402 is welded with a dredging arc plate 403 .

[0045] When the plastic product slides out of the through groove of the separation arc plate 502, multiple clearing arc plates 403 can be operated to move into the through groove of the separation arc plate 502, and then multiple toggle plates 402 can be operated to move back and forth, so that multiple clearing arc plates 403 can follow the movement for clearing, thereby avoiding the blockage of plastic products.

[0046] See Figure 3 , shows a schematic diagram of an embodiment of the present invention for rubbing a plastic product in water, further,

[0047] The device further includes a rubber block 105 bonded to the inclined panel 101 .

[0048] After the plastic product is cut, the multiple toggle plates 402 can be operated to contact the rubber block 105, and the inclined plate 101 can be moved downward so that the rubber block 105 at the lower end of the inclined plate 101 is pressed on the plastic product in the water. Then, the multiple toggle plates 402 are operated to move back and forth, so that the bottom surface of the rubber block 105 is deformed by force, thereby squeezing and kneading the plastic product, thereby improving the cleaning effect.

[0049] See Figure 2-3 , showing the intention of an embodiment of the present invention to facilitate the operation of the inclined panel 101 to move, further,

[0050] The device also includes a connecting vertical plate 104 slidably connected to the inclined plate 101 , a hydraulic cylinder is fixedly connected to the connecting vertical plate 104 by bolts, a telescopic rod of the hydraulic cylinder is fixedly connected to the inclined plate 101 by bolts, and two threaded holes are provided on the connecting vertical plate 104 .

[0051] The connecting vertical plate 104 is connected to a slider that can slide along the cleaning container through two threaded holes, so that the inclined plate 101 can move horizontally along the cleaning container. When the cleaning container needs to move vertically, the telescopic rod of the hydraulic cylinder can be operated to extend and retract, thereby operating the inclined plate 101 to move in the vertical direction.
